mantra

A mantra (Pali: mantra) or mantram (Devanagari: मन्त्रम्) is a sacred utterance, a numinous sound, a syllable, word or phonemes, or group of words in Sanskrit, Pali and other languages believed by practitioners to have religious, magical or spiritual powers. Some mantras have a syntactic structure and literal meaning, while others do not. At its simplest, the word ꣽ, ॐ (Aum, Om) serves as a mantra, it is believed to be the first sound which was originated on earth. Aum sound when produced creates a reverberation in the body which helps the body and mind to be calm. In more sophisticated forms, mantras are melodic phrases with spiritual interpretations such as a human longing for truth, reality, light, immortality, peace, love, knowledge, and action. Some mantras without literal meaning are musically uplifting and spiritually meaningful. The use, structure, function, importance, and types of mantras vary according to the school and philosophy of Jainism, Buddhism, Hinduism, and Sikhism. In Japanese Shingon tradition, the word Shingon means mantra. Mantras serve a central role in tantra. In this school, mantras are considered to be a sacred formula and a deeply personal ritual, effective only after initiation. In other schools of Hinduism, Buddhism, Jainism or Sikhism, initiation is not a requirement.
